In MPFR, we use that together with -pedantic-errors mainly for testing purpose, to ensure that MPFR still builds on a C90 or C99 platform, e.g. all non-portable extensions that we use should be optional. And conversely, we do not want to require -ansi or --std=c99, because extensions are useful for efficiency or for some special features (e.g. logging). -- Vincent Lefèvre <vincent@xxxxxxxxxx> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon) _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
